This Utility Patent Application is a non-provisional application of U.S.Ser. No. 61/891,703, filed Oct. 16, 2013, which is incorporated hereinby reference.

BACKGROUND

One or more embodiments of present application provide a novel canisterstorage system, mixing system, canister assembly, dispensing system, andtracking system. In one or more embodiments, the systems are used forstoring, mixing and dispensing fluids or powders. In one application,the fluid includes one or more paint toners. In one embodiment, systemsand devices disclosed lend themselves for use with fluids or powdersthat need to be measured, and in one example, precisely measured insmall amounts as part of a formula.

Accurate color match in the paint mixing room requires the eliminationof sources of color match errors within the mixing room's control. It isimportant that the painter select the correct formula, adjust theformula for color variation (for example with a spectrophotometer),properly agitate paint toners prior to placement in service, agitatetoners prior to pouring, and pour the toners accurately. Further, it isimportant to minimize the loss of solvent in a paint container tomaintain toner strength. Failure to perform one or more of these stepscan result in poor color match, lower productivity, and additionalpaint, material, and recycling costs.

One known paint storage system stores paint containers in a daisy-wheelconfiguration. The whole wheel is rotated to agitate toners stored inpaint containers positioned around the daisy-wheel. Due to thedaisy-wheel configuration, this type of paint storage system requires alarge amount of space within the paint mixing room.

Another known paint storage system stores paint containers in a rackconfiguration. Each paint container requires a special lid that includesa paddle for periodic mixing of paint toners, and a pour spout fordispensing of the paint toner.

For these and other reasons, there is a need for the present invention.

DETAILED DESCRIPTION

In the following Detailed Description, reference is made to theaccompanying drawings, which form a part hereof, and in which is shownby way of illustration specific embodiments in which the invention maybe practiced. In this regard, directional terminology, such as “top,”“bottom,” “front,” “back,” “leading,” “trailing,” etc., is used withreference to the orientation of the Figure(s) being described. Becausecomponents of embodiments can be positioned in a number of differentorientations, the directional terminology is used for purposes ofillustration and is in no way limiting. It is to be understood thatother embodiments may be utilized and structural or logical changes maybe made without departing from the scope of the present invention. Thefollowing detailed description, therefore, is not to be taken in alimiting sense, and the scope of the present invention is defined by theappended claims.

Although embodiments or examples described in this specification mayrefer to one or more paint systems, it is recognized that the storage,mixing, and dispensing systems and devices disclosed may be used withany type of fluid, powders, or mixtures.

Examples include pharmaceutical, food, chemicals, or automotive anddecorative paint. The systems and devices may be used for measurement offluid or powders, especially precise measurements of small amounts, forthe mixing of color or non-color purposes. The systems and devices canbe used to disperse a desired amount of fluid or powder materialsaccurately, including when it is not part of a formula. For example, itmay be used to disperse amounts of medicine of additive (premixed ornot) into a bottle. The systems may be used to dispense large amounts orsmall amounts (less than one gram).

One or more embodiments provide the next generation of paint dispensingtechnology that represents an evolutionary step in achieving accuratecolor matches compared with existing technology. The storage, agitationand dispensing system addresses all the primary sources of color matcherrors leading to lost productivity and additional paint and materialcosts.

The paint storage and mixing system in accordance with the presentapplication can utilize a soft agitation concept when operated in anagitation mode. As disclosed herein, soft agitation operatescontinuously to keep toner pigments uniformly suspended in a tonercanister, ready for use at any time. As such, there is no waiting forcompletion of an initial or midday fifteen to thirty minute agitationcycle prior to use. Alternatively, the agitation mode may provide forcontinuous rotation, slow rotation, fast rotation, or intermittentrotation of the canisters or containers.

The present application provides for the precise dispensing of fluid toformulate precise fluid ratios. Additionally, the systems disclosed canbe used in non-color applications.

It is to be understood that the features of the various exemplaryembodiments described herein may be combined with each other, unlessspecifically noted otherwise.

FIGS. 1-9 illustrate various views of one or more embodiments of astorage and mixing system, including one or more canisters positionedwithin a mixing bank for storing and maintaining a preferred state formaterial stored within the canister. In one embodiment, paint toner isstored in the mixing system canisters and maintained in a state readyfor use. In one application, the paint toner is used in an auto bodyshop. In other applications, the paint is used for other purposes.

FIG. 1 illustrates one embodiment of a paint storing and mixing systemat 100. System 100 includes a receiving assembly 102 positioned within ahousing 103, the receiving assembly 102 being rotatable about alongitudinally extending axis of rotation 104, indicated by rotationarrow 106. One or more paint canisters 108 are removably coupled to thereceiving assembly 102. Each paint canister 108 includes a first end110, a second end (not shown in this figure), and a sidewall 114extending between the first end 110 and the second end. The receivingassembly 102 stores and agitates (i.e., mixes) paint toner contained inthe paint canister 108 in a position where the sidewall 114 is generallyorthogonal to the longitudinal axis 104.

The system 100 includes a control system 120 operably coupled to thereceiving assembly 102, indicated at 122. The control system 120operates to rotate the receiving assembly 102 about the longitudinalaxis 104. Control system 100 includes an actuation mechanism forrotating the receiving assembly about the longitudinal axis 104. In oneexample, the actuation mechanism includes at least one of a hydraulicactuator, a pneumatic actuator, or an electrical actuator.

The control system 120 operates to move the receiving assembly 102 inone or more modes of operation. In one example, the control system 120operates the system 100 in an agitation mode 126 or a presentation mode128. A user control 124 is provided to change between the agitation mode126 or the presentation mode 128. The user control 124 may be located onthe system 100 (for example, the housing 104), or may be located remotefrom the housing 104.

In other embodiments, system software can be used to control the mode ofoperation. Software can be used to automatically move the receivingassembly 102 to the presentation mode, based on select criteria such asa mixing formula, or to restart the agitation mode. Further, other modesmay be programmed, such as a service mode, or continuous, fast, slow orintermittent rotation mode.

In the agitation mode 126, the receiving assembly 102 is rotated aboutlongitudinal axis 104, thereby mixing the paint toner located incanisters 108. Control system 100 can be programmed to rotate thereceiving assembly (including the paint canisters) according to a numberof predefined parameters, such as speed of rotation, frequency ofrotation, amount of rotation, direction of rotation, etc. Typically, thepaint canisters will be in a presentation position prior to starting theagitation mode. In the presentation position, the canisters are in afront position and accessible to a user. In one example, the canistersinclude labels that are readable in the presentation position. Thelabels may be a visual label, such as a physical label secured to thecanister, and/or an electronic label that can be read by an electronicsystem (e.g., an RFID tag). From the presentation position, thecanisters may be removed from the system 100 for use such as for fillinga paint container or refilling the canister with paint. In theillustration of FIG. 1 , the canisters are in a presentation position.

In one embodiment, in the agitation mode, the receiving assembly (andpaint canisters) is rotated in a first direction 106 a, about thelongitudinal axis 360 degrees in 15 minutes, then in a second (opposite)direction 106 b about the longitudinal axis 360 degrees. In one exampleillustrated in FIG. 2 at 140, the receiving assembly is rotated a totalof 12 degrees every 30 seconds, indicated at 142. The receiving assembleis rotated for approximately 3 seconds to move 12 degrees, then pausesfor approximately 27 seconds, indicated at 144. This sequence isrepeated until the receiving assembly, and canisters positioned withinthe receiving assembly, have rotated a full 360 degrees. This results ina revolution of 360 degrees every 15 minutes, and 4 revolutions perhour. It is recognized that the control system 120 may be programmed torotate the receiving assembly and canisters at different speeds,directions, and durations to achieve a desired agitation result. Forexample, in another embodiment in the agitation mode the canisters arerotated a total of 180 degrees in one direction over a desired timeperiod, then rotated 180 degrees in an opposite direction over a desiredtime period to continuously agitate paint toner contained in thecanisters. The presentation mode itself is also programmable. In oneexample, the presentation mode is activated and the receiving assemblyis moved to a presentation position for 15 minutes, then returned to theagitation mode. In other examples, the presentation mode is programmedto move to the presentation position for other periods of time, or untilthe agitation mode is again activated.

At any time during the agitation mode 126, the presentation mode 128 maybe activated. Upon activation of the presentation mode 128, theagitation mode 126 is stopped and the receiving assembly 102 isimmediately moved to the presentation position. Once in the presentationposition, the canisters are available to be removed for use, or theagitation may be restarted. In one example illustrated in FIG. 1 ,system 100 includes user control 124 to change the system between theagitation mode 126 and the presentation mode 128 by simply pressing abutton.

System 100 further includes a torque release 132. If a high torquecondition is detected by torque release 132, the receiving assembly isdisengaged from the control system actuator. The torque release 132protects against possible over torque situations that may result in harmto the system 100. In one example, torque release 132 is located onhousing 103 and includes a torque limiting clutch coupled to a gearassembly or drive assembly.

FIG. 3 illustrates one embodiment of control system 100 mixing a paintcanister 108. System 100 is able to be contained within a much smaller“footprint” than typical paint mixing systems. The size of the housingthat contains the receiving assembly and paint canisters is only limitedby a rotational diameter D of the largest paint canister. The rotationaldiameter D is defined by the length of the paint canister. In oneexample, the largest paint canister in system 100 is sized to hold 4liters of paint. When rotated about a longitudinal axis 104, thisresults in only a rotational diameter D equal to about 16 inches.

Paint canister 108 is illustrated in a first position 150, at 0 degrees.This location is at a presentation position in the presentation mode.The longitudinal axis of rotation 104 is orthogonal to the canister 108sidewall 114, and extends through the middle (i.e., center) of thecanister. In the agitation mode, canister 108 is rotated in acounterclockwise direction about longitudinal axis 104, illustrated byrotational arrow 152. Canister 108 is illustrated (using dashed lines)in a second location 153 as it rotates past 90 degrees (from thepresentation position). Since canister 108 is rotated at its centerabout longitudinal axis 104, it takes up limited space within housing103. The space for agitation and mixing of canister 108 is onlyrotational diameter D, defined by the rotational length of the canister.

FIG. 4 illustrates another embodiment of the rotation of canisterswithin system 100. Canisters 108 a and 108 b are about one half the sizeof canister 108 illustrated in FIG. 3 . Even though canisters 108 a and108 b are smaller than canister 108, they can all be located within thesame storage system 100 shelf and rotated within the same storage space.As illustrated, canister 108 a and canister 108 b are positionedorthogonal to longitudinal rotational axis 104, with sidewalls 114 a and114 b spaced adjacent to the axis 104. As canister 108 a and canister108 b are rotated from a first, presentation position 156 to a secondposition 158 during agitation, it can be seen that they continue torotated within a rotational diameter D. As configured, this is the samerotational diameter D for larger canister 108 that is positioned withthe longitudinal axis 104 extending through a center of the sidewall 114illustrated in FIG. 3 . Canisters 108, 108 a and 108 b can all belocated within the same storage system 100 shelf with a space constraintthat is limited by the rotational diameter of the largest containercontained in the shelf.

Further, it is recognized that many canisters can be located indifferent configurations within the system 100. FIG. 4 a illustratesexample canister configurations that can be used with the present system100, indicated as canisters 108 shown relative to axis 104.

FIG. 5 illustrates one embodiment of a paint storage system 200contained within a shelf unit 260. Paint storage system 200 can besimilar to the paint storage system 100 previously described herein. Thepaint storage system 200 includes receiving assembly 202 positionedwithin housing 203, the receiving assembly 202 being rotatable about alongitudinally extending axis of rotation 204, indicated by rotationarrow 206. One or more paint canisters 208 are removably coupled to thereceiving assembly 202. Each paint canister 208 includes a first end210, a second end (not shown in this figure), and a sidewall 214extending between the first end 210 and the second end. In one example,the receiving assembly 202 stores and agitates (i.e., mixes) paint tonercontained in the paint canister 208 in a position where the sidewall 214is generally orthogonal to the longitudinal axis 204.

Housing 203 includes a generally rectangular frame 205. The frame 205can be made of a metallic or nonmetallic material. Receiving assembly202 is rotatable relative to frame 205. In one example, receivingassembly 202 includes a small rod 216 located along the center axis ofrotation 204. The rod 216 extends through a sidewall 217 of housing 203,for coupling the receiving assembly to actuation mechanism 218. In oneexample, the actuation mechanism 218 is a hydraulic actuation mechanismand includes a gear assembly 220 couple to a hydraulic drive 222. Theactuation mechanism 218 is part of a larger control system 230 thatoperates storage system 200 in one or more user modes, that may includean agitation or presentation mode previously described.

Receiving assembly 202 includes a first bay 232, a second bay 234, and athird bay 236. First bay 232 is illustrated without any canisters. Asseen in first bay 232, receiving assembly 202 includes a first edge 238and a second edge 240. A coupling member 242 is located at the firstedge 238 and the second edge 240 for removably engaging a receiverpanel. The receiver panels operate to hold a canister in a desiredposition during operational modes of the storage system, such as theagitation mode and presentation mode previously described herein. One ormore examples of receiver panels in combination with paint canisters aredescribed in further detail later in this application. As used herein, areceiver cell is a location within the receiving assembly that includesa receiver panel and canister.

Reference is also made to FIG. 6 , which illustrates a number ofreceiver cells 248 ready to be positioned within the receiving assembly202. In one embodiment, canisters 208 include large canisters 250 andsmall canisters 252. In one example, bay 234 has large canisters 250contained therein. Each large canister 250 is removably attached to areceiver panel 254. In turn, each receiver panel 254 is secured toreceiving assembly 202 via coupling member 242. In one embodiment,coupling member 242 includes a metal edge under tension that secures areceiver panel 254 against the receiving assembly 202 first edge 238 andsecond edge 240. As illustrated, bay 234 is sized to hold three largecanisters 250. The canisters 250 are shown in a presentation positionwhere they are available for use and removable from the storage system200.

Small canisters 252 are illustrated positioned within bay 236. Asillustrated, two small canisters 252 are positioned within each receiverpanel 260. Further, since receiver panels 260 are smaller than receiverpanels 254. Three receiver panels 254 with large canisters 250 fit inbay 234. Four receiver panels 260 with a total of eight small canisters252 fit into bay 236. In one example, the large canisters hold aboutfour times as much paint as the small canisters. Other canisterconfigurations can be used within the receiving assembly. See, forexample, FIG. 4 b . The canisters may range in being very small in size(e.g., 0.1 liter) to very large in size (multiple liters).

FIG. 7 illustrates one embodiment of a paint storage system, includingan expanded view of actuation mechanism 218. The actuation mechanism 218is a hydraulic actuation mechanism. In one example, the hydraulicactuation mechanism includes gear assembly 220 and hydraulic drive 222.Actuation mechanism 218 rotatably couples to receiving assembly 202 forrotation of paint canisters in an agitation mode.

In one example, actuation mechanism 218 includes hydraulic drive 222having a hydraulic cylinder 270, and gear assembly 220 including firstgear 272 having first gear teeth 273, reinforcing plate 274, and secondgear 276 having second gear teeth 277. In assembly, second gear 276 isattached to rotatable shaft or rod 216, indicated at 280. First gear 272is a sector gear, and is direct coupled to hydraulic cylinder 270,indicated at 282. Reinforcing plate 274 is coupled to both the hydraulicpiston 270 and the first gear 272, indicated at 284 and 286. First gearteeth 273, located on a back side of first gear 272, are engaged withsecond gear 276 via second gear teeth 277.

In operation, hydraulic piston 270 operates as a linear actuator,indicated by directional arrows 288. The actuation mechanism 218 isoperated via the control system (not shown), causing hydraulic cylinder270 to move in a linear manner. The hydraulic cylinder 270, in turn,provides movement to first gear 272. Since first gear teeth 273 areengaged with second gear teeth 277, movement of first gear 272 causessecond gear 276 to rotate which also rotates the receiver assembly viarotatable shaft or rod 216.

FIG. 8 illustrates another embodiment of a paint storage and mixingsystem generally at 300. Storage system 300 is similar to storagesystems 200 and 100 previously described herein. In this embodiment, oneor more modular shelves are stacked to form a mixing bank. In oneexample, the modular shelves are stacked vertically upon each other,with the bottom shelf being positioned on a base. In other examples, theshelves may be stacked in alternative manners such as longitudinallyadjacent each other. The mixing bank forms a rack system for storage andmaintenance of paint canisters. Any number of shelves can be included inthe mixing bank.

In the example illustrated, the paint storage system 300 includes firstshelf 310, a second shelf 312, a third shelf 314, a fourth shelf 316,and a fifth shelf 318. With reference also to FIG. 9 , paint storagesystem 300 is a modular, stackable system, with second shelf 312 stackedon first shelf 310, third shelf 314 stacked on second shelf 312, fourthshelf 316 stacked on third shelf 314, and fifth shelf 318 stacked onfourth shelf 316. First shelf 310 is positioned on a base 290. Base 290can be used to house additional mechanical or electrical elements, andalso provide additional clearance to the storage system 300.

Each shelf 310, 312, 314, 316, 318 can be similar or even identical,except that one shelf (shelf 310) includes an actuation mechanism 218that has a drive 222. Only one drive is needed for agitation of thepaint canisters positioned in the whole storage system 300. In theexample illustrated, shelf 310 includes drive 222 operably coupled togear assembly 220 a, and as previously detailed herein. Each shelf 312,314, 316, and 318 includes a corresponding gear assembly 220 b, 220 c,220 d and 220 e, operably coupled to each other via connecting rodassembly 328. Each gear assembly includes connecting rod pin, indicatedas connecting rod pins 221 a, 221 b, 221 c, 221 d, and 221 e. Connectingrod assembly 328 is formed by connecting rod 330 coupled betweenconnecting rod pin 221 a and 221 b; connecting rod 332 coupled betweenconnecting rod pin 221 b and 221 c; connecting rod 334 coupled betweenconnecting rod pin 221 c and 221 d; and connecting rod 336 coupledbetween connecting rod pin 221 d and 221 e. In operation, the controlsystem operates drive 222 coupled to gear assembly 220 a to rotate thereceiving assembly and canisters contained in shelf 310. Further, sinceconnecting rod assembly 328 couples each gear assembly 220 a, 220 b, 220c, 220 d, and 220 e together, operation of drive 222 also rotates thereceiving assemblies and corresponding canisters in each stacked shelf312, 314, 316, and 318.

In other embodiments, each shelf includes its own drive or a drive isused for 2, 3, or 4 shelves, etc.

In one embodiment, a soft mixing system is used with the mixing bank 300for maintaining fluid contained in each canister in a state ready foruse. In one example, the mixing bank operates to slowly rotate thecanisters about the longitudinally extending axis. Slow rotation of thecanisters may include full rotation around the longitudinally extendingaxis, or a back and forth rotation about the axis. In one embodiment, acanister makes several rotations per day. When paint toners arecontained within each canister, the continuous, intermittent, or timedrotation of the canisters provides for tumbling and mixing of the tonerpigments keeping the canister in a state ready for use.

The soft mixing system 300 may further include a presentation mode aspreviously described. When a user approaches the mixing bank, thecanisters may be in any position as they slowly rotate about thelongitudinal axis. The presentation mode provides for the canisters toimmediately be moved within the shelves to a presentation position witheach canister label readily viewable by the user. The presentation modemay be initiated by the user through the control system, the simplecontrol button located adjacent the mixing bank or via programmedcontrol. Although the soft mixing system 300 may be operating at afirst, slow speed for constant or intermittent rotation and mixing ofthe fluid in the canisters so it is ready for use, the presentation modemay use a second, fast speed (relative to the first speed) forimmediately moving the canisters into a presentation mode for viewingand use. The drive mechanism (that may also include a variable speeddrive) communicates with the control system to provide the first slowmixing speed, then quickly being able to switch to a second faster speedfor presentation of the canisters.

FIG. 10 illustrates a front perspective view of one embodiment of areceiver cell, indicated generally at 500. Receiver cell 500 is suitablefor use with one or more paint mixing, storing and/or dispensing systemsdisclosed in this application. Receiver cell 500 includes a first paintcanister 502 and a second paint canister 504 positioned within receivingpanel 506. First paint canister 502 and second paint canister 504 arepositioned within receiving panel 506 by “twist locking” them intoposition. In one example illustrated, first paint canister 502 is in alocked position and second paint canister 504 is in an unlockedposition.

Reference is also made to FIG. 11 illustrating a rear perspective viewof one embodiment of a receiver cell 500, and FIG. 12 and FIG. 13generally illustrating a top and bottom perspective view of a paintcanister, such as paint canister 502. It is noted that the paintcanisters used in the paint storage, mixing and dispensing systems aredescribed in greater detail later in the application. Paint canister 502includes a first locking tab 510, and a second locking tab 511. In orderto lock canister 502 in receiver panel 506, a user grabs handle 512 at afirst end 514 and inserts the canister 502 second end 516 through theopening 518 in the receiver panel. First locking tab 510 and secondlocking tab 511 are inserted into locking slots 520 and 522respectively. By pushing forward and twisting the canister 502 in aclockwise direction, the canister 502 is twist locked into position inthe receiving panel 506.

For smaller canisters, multiple canisters can be located on a singlereceiving panel. In one example, first canister 502 and second canister504 are sized to contain two liters or less of a fluid. The canisters502, 504 are spaced symmetrically about a receiving panel center 524.For larger canisters, a single canister is positioned at the center 524of a receiving panel (as illustrated in one or more previous Figures).One embodiment of a larger canister is illustrated in FIG. 14 and FIG.15 , indicated at 530. Canister 530 is similar to the canisterspreviously described herein, such as first canister 502 and secondcanister 504, and further includes a side handle 532. Since the canister530 is larger in size, side handle 532 aids in positioning canister 530in a receiving panel, locking the canister 530 in the receiving panel,and subsequently removing the canister 530 from a receiving panel foruse. In one embodiment the side handle 532 is generally knob shaped, andis located along sidewall 534 near locking tab 536. Alternatively,canister 530 may not include a second handle. In one example, canister530 is sized to contain 4 liters or more of liquid.

FIG. 16 illustrates a front perspective view of one embodiment of areceiver panel, indicated as receiver panel 506. Receiver panel 506 hasa generally planar top layer 538 that includes a first opening 540 and asecond opening 542. First opening 540 and second opening 542 arecircular shaped, and sized to receive a corresponding canister. Firstopening 540 includes a sidewall 544 that has a cylindrical interiorsurface. The sidewall 544 extends deeper than a back support 546. Tabslot 520 and tab slot 522 are located at opposite sides of the firstopening 540, and are sized to receive a corresponding canister lockingtab.

Tab slot 520 is configured to include a locking mechanism 548 for twistlocking and retaining a canister locking tab. In one example, thelocking mechanism 548 includes a locking arm and spring assembly to aidin retaining a canister locking tab that is moved between a firstposition at 550 with a locking tab inserted in tab slot 520, and asecond locking position, indicated at 554 by dashed lines and bydirectional arrow 556. Similarly, tab slot 522 includes a lockingmechanism 548 c.

Second opening 542 includes a sidewall 544 a, locking slots 520 a and520 b, and locking mechanisms 548 a and 548 b located at respective tabslots 520 a and 520 b.

In one example, the locking mechanism 548a, 548 b includes a locking arm and spring assembly to aid in retaininga canister locking tab that is moved between a first position with alocking tab inserted in tab slot 520 a, and a second locking position,indicated at 554 a by dashed lines and by directional arrow 556 a.

FIG. 17 illustrates another front perspective view of the receiver panel506 of FIG. 16 , including a side view of tab slots 520 and 520 a, eachincluding a corresponding locking mechanism 548 and 548 a. FIG. 18illustrates a partial enlarged perspective side view of lockingmechanism 548. Additionally, FIG. 19 , FIG. 20 and FIG. 21 illustrate asimplified side elevation view of the operation of a locking mechanismsimilar to locking mechanism 548.

Locking mechanism 548 includes a locking arm 560 including a first end562 and a second end 564, and a retainer 565. Locking arm 560 isrotatably coupled to the retainer 565 at second end 564. In one example,locking arm 560 increases in thickness from the first end to a midpoint,indicted at 566. The locking arm 560 then maintains a substantiallyuniform thickness between the midpoint 566 and second end 564. Retainer565 includes a generally cup shaped spring receiver 571 for retention ofa spring 570. The spring 570 is positioned between the locking arm 560and the retainer 565, and maintained in a position between first end 562and midpoint 566. The locking mechanism is located within tab slot 520,within an area defined by a recess 568 in sidewall 544 and a bottom side569 of planar top layer 538. A bayonet fitting or protrusion 572 extendsfrom bottom side 569 at a location proximate the middle point 566.

FIG. 19 illustrates the position of a locking mechanism when a canisteris not located in receiving panel 506, and as such, a locking mechanismlocking tab is not located within the tab slot 520. Spring 570 operatesto push up locking arm 560 against protrusion 572. In reference to FIG.20 , in use with a canister locking tab, such as first locking tab 510,is inserted in tab slot 520 and pressed downward on locking arm 560(indicated by force arrow F). The downward force on locking arm 560compresses spring 570 and creates a space between protrusion 572 andlocking arm 560. This compressed state allows the locking tab 510 tomove from a first position 574 illustrated in FIG. 20 , passedprotrusion 572, to a second position 576 illustrated in FIG. 21 .Downward pressure on first locking tab 510 is released, and spring 570operates to provide an upward force against locking arm 560 and movinglocking arm to press upward against protrusion 572. This upward forcemaintains first locking tab 510 (and the associated canister) in alocked position illustrated in FIG. 21 . By applying downward pressureon locking tab 510, spring 570 is again compressed and the locking arm560 is moved downward allowing the locking tab to move from the secondlocked position 576, passed the protrusion 572, to the first unlockedposition 574.

FIG. 22 illustrates a rear perspective view of receiving panel 506.Locking mechanism 548 is illustrated in an exploded view, and operatesas previously described. Receiving panel 506 includes a first end 580and a second, opposite end 582. First end 580 and second end 582 extendbeyond back support 546, and are used by storage unit receiving assemblycoupling members, such as receiving assembly 102 coupling members 242,to retain receiving panel 506 in the receiving assembly.

FIG. 23 illustrates a perspective view of one embodiment of twocanisters about to be locked into a receiver panel. In operation,receiver panel 506 is positioned on a shelf in a mixing bank. Firstcanister 502 is lined up to be inserted into first opening 540 ofreceiving panel 506. Using handle 512, locking tabs 510 and 511 arelined up with and pushed into corresponding tab slots 520 and 522. Thefirst canister 502 is simply rotated clockwise to twist lock it intoposition. Similarly, second canister 504 is lined up to be inserted intofirst opening 542 of receiving panel 506. Using handle 512 a, lockingtabs 510 a and 511 a are lined up with and pushed into corresponding tabslots 520 a and 522 a. The second canister 504 is simply rotatedclockwise to twist lock it into position, suitable for use in the paintmixing system.

FIG. 27 illustrates an exploded view of one embodiment of the interiorand exterior elements of the canister of FIG. 25 and FIG. 26 . Referenceis also made to FIG. 28 that illustrates one embodiment of a cutawayside view of one embodiment of the canister of FIG. 25 , FIG. 26 , andFIG. 29 that illustrates an end view of one embodiment of the canisterof FIG. 25 and FIG. 26 . In summary, FIGS. 28 and 29 illustrate oneembodiment of how all of the elements illustrated in the exploded viewof FIG. 27 fit and work together.

Cap assembly 600 includes valve assembly 610, cap 612, and jam nut 614.Additionally cap assembly 600 includes a threaded bottle neck 640, and aseal member 642. In one example seal member 642 is an o-ring. A bladder644 is contained within bottle body 602. Bladder 644 (also known as abellows or pouch) holds the desired paint toner within canister 590. Inone embodiment, bladder 644 includes a bladder body 646 with a bladderneck 648 extending from the bladder body 646. The bladder neck 648 ishas a smaller diameter than the bladder body. A lip 650, extending widerthan the bladder neck 648, is located at an end of the bladder neck 648.

When assembled for use, the bladder neck 648 can be partially collapsedto fit through the interior of the bottle neck 640. Once expanded backto its original expanded cylindrical shape, the bladder neck 648 fitsinside the threaded bottle neck 640, with only lip 650 extending beyonda first end 652 of the bottle neck 640. Seal member 642 is seated abouta second end 654 of bottle neck 640, and operates to seal between thebottle neck 640 and a first end 620 of the bottle body 602. Once thebottle neck 640 is positioned on the bladder neck 648, the bladder 644can be positioned within bottle body 602. Bottle neck 640 extendsthrough the first end 620 of bottle body 602. Jam nut 614 is threadedonto bottle neck 640 and physically holds the bottle neck 640 in thebottle body 602 when cap 612 is not on the bottle neck 640. Cap assembly600 is threaded onto canister 590 by threading cap 612 onto the firstend 652 of bottle neck 640.

Handle 630 includes bottle bottom 632. A seal member 660 is seated onthe bottle bottom 632. In one example, seal member 660 is an O-ring.Seal member 660 operates to seal between the bottle bottom 632 and thesecond end 622 of bottle body 602. Locking collar 634 fits over handle630, and is threaded onto the second end 622 of the bottle body 602,thereby helping to secure the bottle bottom 632 to bottle body 602.

FIG. 30 illustrates a perspective view of one embodiment of bladder 644.FIG. 31 illustrates a side view of one embodiment bladder 644. Bladder644 includes bladder body 646 and bladder neck 648 having a bladder lip650. Bladder body 646 includes weakened areas or portions 670 and notweakened areas or portions 672. In use, weakened portions 670 providefor bladder 644 to collapse in a predetermined manner. Based on thedesign of the bladder 644, including the position of weakened portions670 at desired locations, the bladder can be collapsed during operationin a predetermined manner that has been defined as being most efficientfor the process. In one example, bladder body 646 includes weakenedportions 670 such that the bladder body is generally bellows oraccordion shaped. Further, when the bladder body 646 is collapsed, itwill do so in a very efficient manner from the bottom upward. It isrecognized that bladder 644 could have other shapes, other or differentweakened areas, or use other methods of collapsing the bladder in apredetermined manner.

Reference is also made to FIG. 28 . In use, canister 590 is positionedin a paint dispenser with paint toner contained in the bladder 644.During dispensing of paint from the canister, pressurized air is broughtinto the interior of the bottle body 602 via one or more air ports 628,629. The pressurized air in combination with the design of bladder 644results in bladder 644 collapsing from the bottom up, in a predeterminedefficient manner. FIG. 31 a illustrates one embodiment of bladder 644 ina collapsed state and an expanded or non-collapsed state.

FIG. 32 illustrates one embodiment of a tip assembly including a valveassembly for use with a canister, indicated as tip assembly 610 andvalve assembly 611.

The tip 684 is attached to the yoke 680, and made ofa non-magnetic material. Further, tip 684 includes an opening 686. Aplunger 688 is positioned inside the tip. The plunger is made of amagnetic-flux permeable material. The plunger 688 includes a stopper 690sized to close opening 686. A spring 692 is positioned in the tip 684that keeps the plunger 688 in a closed position. In one embodiment,plunger 688 is two pieces, and includes a plastic tip, where in oneexample the plastic tip is funnel shaped.

FIG. 33 illustrates one embodiment of tip assembly 610 including valveassembly 611 in an open position for dispensing fluid in a precise,controlled manner. Paint toner is brought into the fluid area 682 undera relative pressure. The pressure may be an induced pressure or simplyby gravity. A cylindrical coil (e.g., a solenoid) 694 is positionedaround the valve assembly 611. In operation when electrified, the coil694 induces a magnetic field in the yoke 680 and the plunger 688,through tip 684. The magnetic field creates an attractive force betweenyoke 680 and plunger 688. When the attractive force exceeds the strengthof spring 692, the plunger 688 moves the stopper 690 away from opening686 allowing fluid to flow through the opening and exit valve assembly611. The valve assembly 611 is closed by removing the magnetic field,resulting in the stopper 690 to again cover the tip 684 opening 686.Another embodiment of a tip assembly including a valve assembly suitablefor use with the systems in this application is disclosed in U.S. PatentApplication Publication No. US 2010/0108723 A1 published May 6, 2010,and incorporated herein by reference.

FIGS. 34-44 illustrate one or more embodiments of a paint dispensingsystem, generally at 700. FIG. 34 illustrates a canister 702 located ina dispensing position for controlled dispensing of fluid contained inthe canister 702. A receiving container 704 is positioned on a scale706. Fluid from the canister 702 is dispensed into the container 704using the pressurized electro-mechanical dispensing system as describedherein. In one embodiment, the dispensing process is a closed loopdispensing process. A reading from the scale 706 is fed back to adispenser control system 708 that in one example includes amicroprocessor based control board. Once a desired amount of fluid isdispensed, the control system 708 ends the dispensing process.

In one embodiment, a container 704 for receiving a desired amount ofdispensed fluid (e.g., toner) is place in the scale 706 positioned on adispenser frame 710. In one example, the container 704 is positioned asclose to the canister 702 dispensing orifice as possible. In adispensing mode, a user can input the desired amount of toner they wantdispensed. In one embodiment, a negative dispensing weight is input toachieve a target weight of zero. The control system 708 operates topressurize the canister 702 bottle. The control system 708 energizes asolenoid assembly 712 solenoid valve to open and dispense fluid. Whenthe desired amount of fluid is dispensed (as determined by the weightscale control feedback signal), the control system operates to close thedispensing valve and no longer pressurize the canister 702 bottle.Canister 702 is then removed and located back in the storage system. Asecond canister, including a second toner for mixing may now bedispensed into the container 704, or the container 704 may be removedand the toner available for use. Alternatively, a scale control systemcould be used for energization of the solenoid valve.

Embodiments provide for a two part electromechanical valve system forprecise dispensing of fluids, as previously described herein. The valveis located on the tip of the canisters, and the solenoid for actuatingthe valve is located on the dispensing frame. This design in combinationwith a pressurized dispensing system provides for precise dispensing ofliquids down to a fraction of a drop or gram, or even smaller amounts.The fluid is fired out of the canister tip assembly orifice and dropsize cut by actuation of the valve, as opposed to traditional gravityflow.
